Which factor presents the highest risk for a child to develop a psychiatric disorder?

Reasoning:

Choice A reason: Attempting to provide hygiene education to a patient in an acute manic state is clinically inappropriate and ineffective. During mania, the patient lacks the cognitive focus and impulse control necessary to engage in structured learning. Hygiene issues are a symptom of the mania, not a lack of knowledge.

Choice B reason: Increasing the dose without first establishing the current serum concentration is dangerous. Lithium has a very narrow therapeutic index, typically 0.6 to 1.2 mEq/L. If the patient is actually taking the medication and the level is already high, an increase could lead to life-threatening lithium toxicity.

Choice C reason: Lithium typically takes 7 to 14 days to reach therapeutic steady-state levels and show clinical improvement. However, if a patient remains highly symptomatic after 7 days on a robust dose like 1800 mg daily, the nurse must investigate medication adherence (cheeking) or subtherapeutic serum levels before adjusting the regimen.

Choice D reason: While monitoring and documentation are standard nursing responsibilities, they do not address the underlying clinical problem. The patient’s safety and stabilization depend on active intervention to ensure the medication is therapeutic. Passive observation allows the manic episode to continue, increasing the risk of exhaustion or injury.

Reasoning:

Choice A reason: Being present only at the end of the meal is insufficient for a patient with anorexia nervosa. These patients are often highly skilled at concealing food, disposing of it in napkins, or hiding it in clothing. The nurse must witness the entire process to ensure the recorded intake is accurate and reflective of actual consumption.

Choice B reason: Constant observation during mealtimes is a standard nursing intervention for eating disorders. This provides emotional support, prevents ritualistic eating behaviors, and ensures the patient does not hide or discard food. Maintaining a therapeutic presence helps reduce the anxiety associated with caloric intake and ensures the safety and accuracy of the nutritional plan.

Choice C reason: Periodically checking in allows the patient opportunities to engage in disordered behaviors such as "pocketing" food or using compensatory measures like excessive water loading. For a patient who has lost 20% of her body weight in 3 months, high-level supervision is required to manage the acute physiological risk.

Choice D reason: Self-reporting is highly unreliable in the acute phase of anorexia nervosa due to the patient's intense fear of weight gain and drive for thinness. Patients may intentionally under-report or over-report intake to avoid intervention. The responsibility for assessment rests with the clinical staff to ensure objective and valid data collection.
